Description
Technical Field
The invention relates to the technical field of ceramic production, in particular to a blended ceramic pigment glaze and a production method thereof, and a stone-like glazed tile and a production method thereof.
Background
The ceramic glazed tile is one kind of building decorating material, especially stone-like glazed tile, and is popular in recent years. The materials of the artificial stone glazed tile on the market are generally obtained by buying the stone, scanning the stone, performing Photoshop post-processing, and printing the stone on a tile blank in a multi-channel ink jet printer printing mode to be fired. The stone-like glazed tile produced in this way has the following defects: compared with the stone scanned by the scanner, the original graph scanned by the scanner loses some original details, and the details are more seriously lost compared with the material stone after the Photoshop post-processing. Thus, the imitated glazed stone tile becomes unreal and has a gap compared with the real stone. The common problems of the stone-like glazed tiles in the current market are unreal, unnatural, rigid and inflexible, so that the development of the stone-like glazed tiles is still in a standstill.
Along with the improvement of the living quality level of people and the continuous improvement of the aesthetic value of people, the original production process can not meet the requirements of consumers any more. The stone-like glazed tile is at the stage of stepping in situ at present, and even the aesthetic fatigue caused by the process causes consumers to feel that the difference between the stone-like glazed tile and the real stone is too large. Although the stone material can be restored to the characteristics and lines as far as possible by the assistance of advanced equipment and the supplement of new materials, the stone material is far from the real stone material.
In view of this, the invention is particularly proposed.
